Answer:

408

Step-by-step explanation:

You would set up a proportion of 1/12 = 34/x. You would do the butterfly method and get 1x=408. Then divide 408 by 1 to get 408.

Answer:

408

Step-by-step explanation:

You see the rate is one out of twelve(1/12)

So if 1 now equals 34 (ALWAYS KEEP THE FRACTIONS BALANCED, WHAT YOU DO TO ONE SIDE YOU MUST DO TO THE OTHER)

so to get 1 to 34 you multiplied by 34. So do the same to 12 to get your total number or surveyed students.

Hope I helped!

A number is equal to twice a smaller number plus 3. Yhe same number is equal to twice the sum of smaller number and 1. How many
allsm [11]

Answer:

There is no solution to the problem

Step-by-step explanation:

In order to find the solutions to the problem you can write the situation in an algebraic form.

You have that a number is equal to twice a smaller number plus 3. This can be written as follow:

x=2y+3      (1)

where x is the number and y is the smaller number

Furthermore, the same number x is equal to twice the sum of the smaller number and 1, which can be written as follow:

x=2(y+1)     (2)

To find the solution you equal the equation (1) with (2), and you solve for y:

2y+3=2y+1

3=1

You obtain an inconsistency, hence, the situation of the problem does not have solution
